Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed September 18. 1905. Serial No. 278,933.

To ctZZ whom it may concern.-

Be it known that I, ETHAN I. DonDs, a citizen of the United States,residing at Pullman, in the county of Cook and State of Illinois, haveinvented certain new and useful I'mprovements in Corner-Stakes for Carsand Method of Manufacture, of which the following is a specification.

To provide an improved form of car-stake which shall combine greatstrength, pleasing appearance, and economy of manufacture, I haveinvented the form of stake and the method of producing it hereinafterdescribed and claimed. My invention relates more particularly tometallic corner-stakes for railway-cars, but is not limited to suchapplication, and by my method I am enabled to manufacture two or more ofsuch stakes simultaneously. When two stakes are to be made from a sheetof metal, I e'mbo ss or press out of the plane thereof two hollow ribsand bend up the outer edges of the sheet to form flanges, the twostakes'thus produced. being subsequently cut apart, so that each has arib and angularly-disposed flanges.

In the accompanying drawings I have illustrated the method ofmanufacturing these stakes and also the stakes themselves.

Figure 1 illustrates a cross-section of the dies employed in pressing asheet of metal so as to form two of my improved stakes, and shows asheet of metal between the dies. Fig. 2 is an end view of the sheet ofmetal after it has been pressed by the dies. Fig. 3 is an edge view ofone of the stakes. Fig. 4 is a horizontal cross-section of a portionof-a car and corner-stake and illustrates the manner in which the stakeshown in Fig. 3 is appliedto the corner of the car. Fig. 5 shows theapplication of the reversely-formed stake to the other end of the car,and Fig. 6 is a perspective view of the sheet of metal after it has beenoperated upon by the dies.

Referring to Fig. l, the lower die 10 has a central horizontal surface11 and two separated vertical surfaces 12 and 13. Between the centralhorizontal surface 11 and the vertical surface 13 is a taperedtransverselyrounded projection 14, and between the cen tral horizontalsurface 11 and the vertical surface 12 is a tapered transversely-roundeddepression 15. The upper die 16 is provided with a central horizontalsurface 17 and vertical surfaces 18 and 19, together with a ta peredtransversely-rounded projection 20,

adapted to lit in recess 15, and a tapered transversely-rounde l recess21, within which projection 14 is adapted to fit. A rectangular sheet ofmetal 22 is placed between the dies which are subsequently broughttogether, pressing the sheet into the shape illustrated in Fig. 6. Sheet22, when thus formed to shape, has a central horizontal portion 23, withtwo tapered hollow ribs 23 and 23 pressed out of the plane thereof inopposite directions, the narrow ends of the ribs pointing in oppositedirections, the sheet also having the vertical flanges 24 and 25, theouter edges of which are somewhat concaved by the stamping operationwhich draws in the metal to form the ribs. It will be seen that the ribs23 and 23 are tapered not only in width but also in thicknessthat is,the amount they project from the plane of the sheet. To cut the sheetinto proper shape so as to form two corner-stakes, it is sheared on line26 and the vertical flanges 24 and 25 are trimmed on lines 27 and 28.This produces two reverselyformed corner-stakes, each with twoangularly-disposed flanges and an integral hollow tapered rib.

Fig. 3 is an edge view of one of these stakes. The same is secured tothe corner of the car by means of rivets or bolts passing through holesin the stake flanges and through the end of the car 29 and side of thecar 30, preferably engaging upon the inner side an angle-bar 31. It willbe noted that the two stakes 32 and 33, formed simultaneously by thisprocess, are not alike, but are, in fact, reversely shaped, beingadapted for use on the opposite ends of the car, as shown in Figs. 4cand 5.

Although I have illustrated and described a process of making two stakessimultaneously, it will be apparent that by properly shaping the diesany number of such stakes may be produced by one stamping operation, thealternate ribs projecting in opposite directions from the plane of thesheet and having their narrow ends extending toward the opposite ends ofthe sheet.

It will also be obvious that other minor changes may be made in thisprocess or in the stakes themselves without departing from the substanceof the invention as defined in the appended claims.

This patent is intended, to embrace only so much of the disclosure madeherein as is covered by the claims.
